Welcome to the group.  Alot of useful (and some not so useful) info here.  I 
have had great success using CS for a chronic sinusitis.... I just put half a 
dropperfull of 10ppm home made ionic silver and distilled H2O into each nostril 
as I lay on my back... let it sit for a few minutes while I move my head gently 
from side to side.  Did that a couple of times a day for a few days and cleard 
my sinusitis that I had had for many years.
